spring - 属性文件中的 persistence.xml 属性值

Question

我对entityManger有以下配置

<jee:jndi-lookup id="dataSource" expected-type="javax.sql.DataSource"
                     jndi-name="java:jboss/datasources/AppDS"/>

<jee:jndi-lookup id="entityManagerFactory"
                     expected-type="javax.persistence.EntityManagerFactory"
                     jndi-name="java:comp/env/persistence/appPersistenceUnit"/>

我还有 persistence.xml 文件，现在我想向我的应用程序添加 hibernate 搜索功能，因此我在 persistence.xml 文件中添加了以下属性..

<property name="hibernate.search.default.directory_provider" value="filesystem" />
<property name="hibernate.search.default.indexBase" value="/var/lucene/indexes" />

这里我想将indexBase属性值外部化到属性文件中，就像这样。

<property name="hibernate.search.default.indexBase" value="${index.location}" />

任何人都可以建议我如何实现这一目标吗？

我使用的是 Spring 版本:4。

谢谢。

更新 - 2我已将以下代码添加到我的 application-context.xml

评论了此内容

<jee:jndi-lookup id="entityManagerFactory"
                         expected-type="javax.persistence.EntityManagerFactory"
                         jndi-name="java:comp/env/persistence/appPersistenceUnit"/>

并添加了以下 bean 配置..

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
        </property>
        <property name="jpaProperties">
            <props>
                <prop key="hibernate.search.default.indexBase">/var/lucene/indexes</prop>
            </props>
        </property>
</bean>

但是服务器重新启动后会出现以下异常..但是如果我在 persistence.xml 中保留相同的属性，它就可以正常工作..

另外，我想检查 LocalContainerEntityManagerFactoryBean 中 configLocation 的用途是什么？

谢谢。

抱歉，我没有在现有的 persistence.xml 文件中提供完整信息hibernate.cache.use_second_level_cache 已设置为 true，并且工作正常。

但是在下一个要求中我必须实现搜索功能，所以我使用了 hibernate-search。我在 persistence.xml 中添加了 hibernate.search.default.indexBase 和 hibernate.search.default.directory_provider ，之后它工作正常。它在实体 checkin 时创建索引，也在实体更新时更新索引。

由于我必须在不同的环境中部署此代码，因此我必须为每个环境指定不同的位置。对于所有环境，我都有不同的属性文件。所以我也想对这个 hibernate.search.default.indexBase 做同样的事情..但是按照您的建议添加实现后，它仍然不起作用..

如果我可以帮助您提供任何其他信息来找出解决方案，请告诉我...

由于 persistence.xml 位于 spring 外部，因此无法通过 spring 属性占位符注入(inject)属性。

继承的方法setJpaProperties斯普林斯的LocalContainerEntityManagerFactoryBean也将解决您所期待的目的。

示例 spring bean 配置如下所示 -

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
  <property name="dataSource" ref="dataSource" />
  <property name="jpaVendorAdapter">
     <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
  </property>
  <property name="jpaProperties">
     <props>
        <prop key="hibernate.hbm2ddl.auto">create-drop</prop>
        <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
        <prop key="hibernate.search.default.indexBase">${index.location}</prop>
     </props>
  </property>

请注意，这仍会通过附加功能从 persistence.xml 读取配置。 (例如 persistence.xml 的自定义位置，而不是默认的 META-INF)
